Question

Find product of
(5x-y+z) (5x-y+ 2]​

Answer 1

Answer:

−10xy−2yz+10xz

Step-by-step explanation:

We know (5x−y+z)(5x−y+z) =(5x−y+z)

2

Using identity (x+y+z)

2

=x

2

+y

2

+z

2

+2xy+2yz+2xz

Here x=5x,y=−y and z=z

Therefore, (5x−y+z)

2

=(5x)

2

+(−y)

2

+(z)

2

+2(5x)(−y)+2(−y)(z)+2(5x)(z)

=25x

2

+y

2

+z

2

−10xy−2yz+10xz
